I’m coming to you because I hope the community can help to solve this problem. I have submit a ticket but at this time nobody have found something to help me. I have the Movi M5 since a lot of month, the Movi have never worked properly. I try to have a good stabilization with a GH4 + 12mm Olympus on my X8 octocopter with a remote controller or only with the follow mode. There is simply no stabilization, it’s like on a boat: the roll, the pan and the tilt are absolutely not fixed. At first I thought it was a vibration problem. I have good balanced all props, changing the o-ring red by the blue, check the good balance of the movi and after all that the problem is still there. After that I spend a lot of time to try a lot of swiftness tuning, with no good result. After making some test with my Rc controller Futaba 14SG and 8J, I have fund a really weird problem: when I make a roll trim, the Movi make a pan with the roll. This is more important when the tilt is down or up. My first thinking was there is a mixed mapping on my controller but after making a lot of mapping test with two controllers the problem is still there. I have start with clean and new plane or helicopter model with no mixed program and the problem is still there. I have test custom mapping, user manual mapping, quadrocopters mapping () and finally freefly model setting file on a sd card that the support send me, and the problem is still there : when there is a roll trim there is a pan with it, or when the roll trim is set at the max, when I do a pitch there is a roll and a pan with it. It's like there is a really weird program mix or a IMU error. The Freefly support say me that it’s a problem of mapping settings, but I have try every mapping possibilities. I have a lot of multicopters and I have built a lot gimbal with alexmoss or phobotic controllers. I’m not a beginner, but not a freefly expert. One day I had a similar problem with a phobotic gimbal and it’s solved by attaching correctly the IMU (if it’s not centered and at the level the roll could be mismatched with the pan and the tilt), maybe the problem is the same or worth. Futhermore a mapping settings problem do not give stabilization problem on a majestic mode with no rc controller. Maybe there is two problems, but after all my test I’m really thinking there is a hardeware problem. You can see on this video the problem: . At first I try the Futaba model file sending by the freefly team for a good mapping and at the end you can see some footage of the gh4 on the movi in majestic mode or dual operator mode in the air. At this time I really need some help. This problem is very weird. I have spent a lot of time and money for a high end technology that doesn’t work. If someone have an idea, I shall very grateful. Thanks a lot! Ps: Sorry for my English.
